The First Experience Of Intel Haswell On Linux

Phoronix: The First Experience Of Intel Haswell On Linux

Haswell is here, Haswell is here, Haswell is here!!! After talking for months about the Linux kernel and driver development for Intel's Ivy Bridge successor, the heatsink can be lifted today on talking about Intel's Haswell processor. For the past few weeks I have been running and benchmarking an Intel Core i7 4770K "Haswell" processor on Linux to mixed success. While the Haswell improvements are terrific, the Linux experience now is awaiting improvements.

So Haswell is slower than Ivy Bridge at the moment? Interesting to know. Given the pace of things, it will probably take until next year to fix most of the issues and propagate the fixes to the distributions.

Just use ubuntu with the xorg-edgers ppa or gentoo. If one uses Debian or RHEL one knows what one gets.

... this was to be expected, thank the half assed effort intel puts into anything non m$. And then they get surprised people are buying arm devices by the truckload.

" here's our cpu, it's $400 .. btw you also need a $200 motherboard for it... and a $100 windows license coz seriously if you are using linux you might as well stick with core duo"

Yeah, I don't think the efforts are half-assed.
I understand why they work the way they do, and am happy at the money they spend on linux. They realise that the near future is with linux (iow, the windows market share ain't gonna get higher), so they have been investing.
I'd be curious to know why power management is causing performance problems unless the problem is that it is hard to remove the proc from a lower power state in linux, or perhaps they are referring to thermal performance?
What makes me a bit sad is that there are some features that linux is gonna have difficulty accessing (like wake on activity from various devices like wlan). Some of that is due to other parts than the kernel, however.
